Solution:

According to the accepted current theory, known as the fluid mosaic model, the plasma membrane is composed of a double layer (bilayer) of lipids, oily substances found in all cells. The fluid mosaic model was first proposed by S.J. The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness.

Thus this is the required answer.

On which of these issues is public opinion less likely to affect policymaking?
11Alexandr11 [23.1K]

Public opinion is less likely to affect fiscal policy making.

There are a number of variables that affect the formulation of a country's fiscal policies, the most important being domestic demand and economic growth.

Public opinion is therefore not a relevant factor that affects the formulation of these policies, it affects more social and environmental policies, for example.

For a better understanding of fiscal policy, we must understand the concept of taxation.

Taxation is a financial obligation on individuals and organizations, whose main objective is to improve the economy and public services so that there is a fairer and more equal society.

Some examples of taxes:

  • Income tax
  • payroll tax
  • sales tax

Therefore, public opinion is more likely to affect the formulation of social and environmental policies than fiscal policies. Because it is capable of instituting new ideas and social awareness that can directly affect legislation.

Imagine a microbial cell that normally carries out aerobic respiration has encountered a low oxygen environment and may die if t
weeeeeb [17]

Answer:

a. Oxygen performs an essential role in the mentioned microbial cell in a manner that it takes part in the procedure of glycolysis, Krebs cycle, and electron transport chain, which eventually assists in the production of energy from food substrates and this generation of energy helps the cell to survive.  

In the existence of oxygen, sugar gets dissociated through glycolysis to generate pyruvate, which again in the existence of oxygen is transformed into acetyl CoA. This moves into the Krebs cycle and gets dissociated to water and carbon dioxide generating ATP through ETC. This generation of ATP helps the cell to survive.  

In low oxygen surrounding or in the absence of oxygen, some of the aerobic microbes can switch their respiratory pathway and carry on the process of fermentation and anaerobic respiration to produce energy and thrive. However, the mentioned microbial cell, which when it comes in contact with the low oxygen environment cannot carry out fermentation process and would die eventually.  

b. This organism can be classified as obligate aerobes as they always need oxygen and do not possess the tendency to carry out the process of anaerobic respiration or fermentation under the absence of oxygenic environment.
